He asks for a last wish to be granted him to see his brother to whom he hands the crucifix along with a note saying that he is to take the pill at 8:10. Lincoln becomes extremely ill and is taken to the infirmary where Dr. Tancredi surmises he is suffering from food poisoning. The prisoners use the prison’s tunnels to reach the infirmary where a pipe previously corroded by Michael with a chemical compound is located. Upon getting under the infirmary, they suddenly realize that the pipe has been replaced and their attempts to remove it are in vain even with the help of Lincoln from above.
